Demand for bus and Rail Analyzing a corridor with a similar Level Of Service 5th Israeli-British/Irish Workshop in Regional Science April, 2007
The Question • Does the higher demand for Rail transit compares to Bus transit is a result of differences in Level Of Service variables or of the Passenger attitude toward the transit technology? The problem • Lack of transit corridors where both transit modes are operated in a similar level of service.
Presentation Outline • Description of the selected corridor • Description of transit Level Of Sercive in the selected corridor • Transit mode split in the selected corridor • Passengers survey conducted in the selected corridor • Survey results and conclusions
Tel Aviv metropolitan area : North section The corridor – Haifa – Tel Aviv Maximum distance between modes is less than 2 km
The corridor – Stations and route Similar service areas for both transit modes Rail: Serves exclusively the Binyamina area Bus: A broader alighting service in Tel Aviv
Level of service – SurveyLimitations • Congestion at sections of Bus route between 7-9 am • Straight rail service was not taken into account
Level of service – Cost and Headway Daily DeparturesTravelCost (in INS) Similar travel cost Similar number of departures, rail frequency is a bit higher in Rush hours
Level of service – In vehicle travel time Travel time comparison* *Rail – Taken from timetable *Bus – Time taken on vehicle In vehicle travel time difference is no more than12 min
Level of service – Comfort Rail Bus Wider seats and tables Privacy advantage
Mode split – Rail and Bus Source: Israel railways counts at Hof Hakarmel st., Survey counts on Buses
The survey – Rationality • Comparison between travel habits in two transit modes which supply similar level of service
The survey – Data collecting • Conducted at the intermodal station inHof Hakarmel between 9-15 • Bus: At the waiting area • Rail: At the platform • Questionnaires were given for all waiting passengers (ap. 5 min needed to fill up the questionnaire) • Passengers that arrive in the last minutes are not included in the survey • Total collected: • Rail: 101 questionnaires • Bus: 107 questionnaires
The survey – The questionnaire • 3 parts: • Trip charasteristics • (13 questions) • 2. Passenger characteristics • (12 questions) • 3. Passengers Attitude • (5 questions)
Results – Passenger characteristics Number of vehicles per Household Income Rail passengers belong to a higher socioeconomic group compare to bus passengers
Results – Travel characteristics Availability of private car Access mode Private car is a dominant mode as an access mode for rail Availability of private car is greater for rail passengers
Results – Rail used where bus should have been preferred Neve tzedek Herzeliya industry area 2500 m 1000 m 500 m 500 m Large share of rail passengers (42%) doesn’t save time when using rail mode
Results – Passengers attitude Satisfaction by mode Reason for choosing the mode Comfort and time cost are the main reasons for using rail mode Large share of bus free riders
Conclusions • Mismatch in the level of service and mode choice • Rail attracts higher income passengers • Large share of rail passengers don’t save time by using rail service • Comfort is the main reason for preferring the rail
Future research • The validity of the assumption that rail level of service embedded in bus will attract the same number of passengers is questionable • The effect of subjective (psychological) factors on the feeling of comfort on bus vs. rail should be investigated
